What's black and white and red all over? Your victims as they're splattered against the wall after being skewered on a lamppost. Or perhaps the answer could include disposing of your enemies in a meat grinder, or playing darts using only your opponents and a baseball bat. Whatever the stylish kill, this video game means serious business on the violence factor. Maybe the blood splatter on a black-and-white backdrop really highlights the ferociousness and gratuitous violence, but any game with flavors of The Running Man and a protagonist with a chainsaw on his arm usually have violent potency.
